to bees, as well as being moderately to highly toxic to birds and toxic to most aquatic life. Naled is also toxic to butterflies at amounts typically used to control mosquitoes. The mule deer is among those most resistant to its effects. Naled is banned in the European Union because of concerns about the toxicity. 2015–16 Zika virus epidemic Aerial spraying of naled has been recommended by the Centers for Disease Control and Prevention and United States Environmental Protection Agency for the prevention of the spread of the Zika virus in the United States. Experts at both the CDC and EPA, as well as independent universities, have argued that naled is safer than other chemicals and should not cause significant health issues due to the low level of exposure. The federal government had considered using the chemical in Puerto Rico to stop the spread of Zika, but decided against it due to the potential danger to pregnant women. Its proposed use against Zika led to protests in Puerto Rico. Miami is using specialized trucks to spray naled and Bacillus thuringiensis israelensis (BTI). Governor Rick Scott said that the CDC recommended using helicopters to spray the insecticides, but some people in Miami and Miami Beach are opposed to aerial spraying. Spraying of naled in Dorchester County, South Carolina purportedly led to the deaths of 3 million honeybees and increased criticism by beekeepers. Beekeepers in the county complained that they had not been notified of spraying before it happened. Juanita Stanley, a beekeeper and co-owner of Flowerton Bee Farm and Supply, told CNN, "Now, I'm going to have to destroy my hives, the honey, all my equipment. It's all contaminated." Jennifer Holmes, vice-president of the Florida State Beekeepers Association, compared the loss of bees to other forms of agriculture, saying, "If there was a regulation that allowed some spraying that would kill half of your livestock overnight, how would you recover?" She went on to say that "we understand the serious threat of possible disease, but we also have to maintain our agricultural livelihood.” See also Malathion - another insecticide sprayed from the air to control mosquitos Bacillus thuringiensis israelensis - a biological control agent sprayed from the air to control mosquitos References Acetylcholinesterase inhibitors Organophosphate insecticides Organochlorides Methyl esters Organobromides
